New MRP G2 Mini SL...redesigned and 30% lighter - Mountain Bike Review. Polycarbonate. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Polycarbonate is also known by a variety of trademarked names, including Lexan, Makrolon, and others.
Structure[edit] Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). Production[edit] The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2. (HOC6H4)2CMe2 + 2 NaOH → Na2(OC6H4)2CMe2 + 2 H2O Na2(OC6H4)2CMe2 + COCl2 → 1/n [OC(OC6H4)2CMe2]n + 2 NaCl Phones[edit] Home Page. 6861-44-9.
The PubChem Project. CAS registry number. CAS Registry Numbers,[1] also referred to as CASRNs and CAS Numbers, are unique numerical identifiers assigned by the Chemical Abstracts Service to every chemical substance described in the open scientific literature (currently including those described from at least 1957 through the present), including organic and inorganic compounds, minerals, isotopes, alloys and nonstructurable materials (UVCBs, of unknown, variable composition, or biological origin).[2] The Registry maintained by CAS is an authoritative collection of disclosed chemical substance information.
Currently the CAS Registry identifies more than 81 million organic and inorganic substances and 64 million protein and DNA sequences,[3] plus additional information about each substance. The Registry is updated with an approximate 15,000 additional new substances daily.[4] Use[edit] Historically, chemicals have been identified by a wide variety of synonyms.
